Oil line routing question???
 

Hey all,

I’m adding an oil filter relocation setup to my 572. I’ve drawn up two ways to do it. Can y’all have a quick look and comment?
I know the question of filtering hot or cooled oil has been brought up. Personally I like the idea of filtering right before it goes into the block, but not sure if that’s really necessary. Hopefully these pictures are adequate. Sorry they ended up uploading sideways. If there is a better way to do it, please feel free to add that.

Thanks.

You really should filter the HOT oil first thing out of the block. Then cooler. Then into the block. Hot oil goes thru the filter much much easier than cooled oil. By placing the filter last before the block your making it your primary restriction.
Secondly, if something goes sideways, and the oil pump is pumping engine glitter, your putting it thru all your lines and your cooler. Potentially blocking the cooler and making a bad situation a catastrophic situation. Then you have to find a way to clean out all that line and your cooler or scrap it.

Like this? Everyone agree?

FYI: The direction oil flows thru the cooler is important. It cools the oil better one way than the other. Can't remember off hand if it's supposed to go with or against the flow of water but someone will likely chime in. If not, a quick search here will tell ya.

It cools better when the flow directions are against each other.

Thx!. Looking back, op has it right in his second pic.

Edit: This is only in regards to the oil/water flow direction thru oil cooler.

I think your very first picture option #1 in post #1 actually has the ability to bypass the oil filter the way it is plumbed if I'm reading it correctly.

Post #3 is how I would do it with a stand alone thermostat.

My opinion… Filter last.

To quote a 9000+rpm 500 mile almost every weekend head of an engine program :

”Debris can come loose in the cooler from manufacturing. Even the highest quality coolers as can have this problem.
Again, the filter is to protect the engine from itself (wear particles) and the system (Debris from manufacturing) be it lines, fittings, cooler or debris entering the system while servicing.”

I add….Hoses too.

Filter right after it comes out of the block, anything else would keep me up at night.
SB ... debris from a cooler, what debris?! maybe 9000 rpm scrambled that dudes brain but I couoldn`tr disagree more.
Filter and colder oil is also dumb .

I only see one way to not filter “cool” oil and that would be the 1st pic. However this would bypass the filter until the thermostat opened up and routed the oil to the filter and then on to the cooler.

The 2nd pic would filter ALL oil cool and hot before it goes into the block.

The 3rd pic would filter ALL oil cool and hot but would do so after it leaves the block.

I think I am more confused now after looking at all 3 options. lol. Everyone thinks filtering cool oil is a bad thing but the only way I see to not filter cool oil would be the 1st pic.

The whole point of the Tstat is to get the oil to temp faster, but this involves returning the oil back to the block to heat it up. So how do you accomplish this AND filter the oil as for awhile it’s going to be cool until it isn’t.

If you have an oil filter with a built in bypass, does it bypass the filter element until the oil heats up?

Thanks all. I’m not disagreeing with anyone, I’m just trying to wrap my head around how you accomplish not filtering cool oil unless you bypass the filter.

‘Thanks
